I am cooking for 35 people this weekend. Doing pulled pork for a lunch for firefighters. I do not think there is bread being served with the lunch. Just beans, potato chips. I was figuring each person eating 3/8 of a lb of pork. Is that about right? I figured ½ lb is to much ¼ lb may be to little since there are not a lot of other sides being offered. I am just cooking the butts. Other people are doing the sides. It is a nine hour coarse and I do not want us to be falling asleep after lunch. A full breakfast will be served to start class off. The BBQ is for a noon lunch.

I do shoulders that weigh (bone in) 8 - 9 pound range. I get 10 - 14 sandwiches out of each one. Thats with bread though. If I were you, I'd go a tad higher maybe 28 - 30 pounds meat being your not serving sandwiches.

The costs for your purchases and for your sales are all customizable as are the yields, my yields normally fall around 55% for pulled pork, more than half the family grumble if they have the slightest bit of fat or jelly.
